    RE: .0

    For the command:

>  SHOW NODE4 BEACT1 USER BYTES RECEIVED, -
>    FOR START (23-AUG-1991:16:00:00) - 
>      UNTIL 23-AUG-1991:16:06:00 EVERY 00:02:00 DURATION 00:01:50, -
>    IN DOMAIN      = .BERN

    you are actually getting the expected results.  The command breaks down
    as follows for the scope of interest time ranges:

    1st time range:  16:00:00 to 16:01:50
    2nd time range:  16:02:00 to 16:03:50
    3rd time range:  16:04:00 to 16:05:50

    There is no 4th time range, as the UNTIL time is the same as the
    beginning time of the "next" time range.

    For EACH of these 3 time ranges, you get back the datum (if any) BEFORE
    the time range, data (if any) included IN the time range, and the datum
    (if any) AFTER the time range.  So your log is showing that this is
    indeed the case, as follows:

    Modifying the SHOW command may give more useable results.  Given that
    the data must be included in the time range defined by the original
    START and UNTIL parameters of the RECORD operation, a simpler SHOW
    command that would display each datum only once would be:

  SHOW NODE4 BEACT1 USER BYTES RECEIVED, -
    FOR START (23-AUG-1991:16:00:00) DURATION 00:06:00, -
    IN DOMAIN      = .BERN

    This command will result in all the data being displayed in order and
    only once.  Note that this relationship between the recording and the
    displaying (the RECORD contains an EVERY component (polling interval)
    and an UNTIL component (possibly NULL = infinity), while the SHOW
    covers, in a single time range (START and DURATION components only),
    the entire scope of interest time) is probably the easiest to deal
    with.  As seen above, putting an EVERY component in the SHOW request
    can be confusing.

Re. 1:  Thanks for your explanation !

I would like to suggest that this should be added in the DECmcc documentation.
In the DECmcc BMS Use manual page 3-2 there is a pointer to the Director Use
concerning the past time specification with the SHOW directive. But in the 
Director Use manual you find only on page 4-21 a pointer to the BMS Use.

Sorry, if I have overlooked something.

I have found a further feature of the DECmcc Historian FM, which caused some
troubles to a customer and me. The behaviour of the SHOW SNMP directive with
a past time specification is case sensitive to the global entity name.
The same with the SHOW RECORDING directive.
